I have tried so many different shoe covers each year. I commute about 30 miles a day by bike and ride on the weekends as well. I go through about three pairs every year cause they either are lacking in some area and I cannot bother to wear them again, or they are so poor in quality I just toss them. I purchased these just before the weather turned this year in Chicago. They have been a life-saver. Heavy rain, sleet, and some snow and these performed amazing! Combo with some deep winter socks and they will keep you warm for those long winter sessions. I have also tried them with summer socks on days in mid-high 30s (farenheit) and are still warm, but not so much that you find yourself sweating 10 minutes into your ride. Must have and I am definitely picking up the tall version for January/February.
